Abstract:
Articles and methods related to the cold-forming of glass laminate articles utilizing stress prediction analysis are provided. A cold-forming estimator (CFE) value that is related to the stress experienced by a glass sheet of a glass laminate during cold-forming is calculated based on a plurality of geometric parameters of glass layer(s) of a glass laminate article. The calculated CFE value is compared to a cold-forming threshold related to the probability that defects are formed in the complexly curved glass laminate article during cold-forming. Cold-formed glass laminate articles are also provided having geometric parameters such that the CFE value is below the cold-forming threshold.
